IMPROVED TRACK-CLEARER.

'ro ALL wieioM rr MAY coNcEENg Be it known that I, ERNESTO ABBIATI, of. the city, county, and State `of New York, have invented a new I and improved Track'and Street-Cleaner; andI do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to -the accompanying drawings,iz`orming part of this specification, iin which- Figure l represents a side elevation, partly in section, of my invention.

Figure 2 is a horizontal sectional view of the same, the plane of section being indicated by the line :c iig. 1.

Figure 3 is a horizontal sectional view ofthe same, the plane of section being indicated by the line-yy, fig. 1.l

This invention relates to a new device forv clearing railroad-tracks and streets from snow, and consists in the use of a revolving horizontal disk carryingoscillating wings, which wings are drawn in and out by the action of crank-shafts revolved by means of gear-wheels from the shaft towhich the disk issecured. This Vshaft is secured to the-front part of a truck, which moves in frontof the locomotive or car, or to the front part of a wagon or car, and receives rotary motion from one of the wheels of the' locomotive, car, or wagon, or from any other suitable device. The disk isl suspended close above the level of the street or above the track to be cleared, and has a cutting-edge, whereby it is enabled to pass easily through the snow, and to separate the same'from the ground or track. The wings, then, as they arrive at the front of the disk, begin to be gradually moved out, and, A

as they arrive at the side, they are moved quite out, and throw the snow, from the disk, over the side of'ithe track. Brushes, moving behind the disk, andin front of the wheels, clear the track completely froinall particles of snow. v 1 l v A represents a vertical shaft, fitted 'through a stationary arm, B, which is secured to the front of a car, or locomotive, or wagon, or tothe front of a truck, C, which is arranged and moves in front of the car, locomotive, or other vehicle. The shaft A is suspended by means of a sleeve, a, which is provided with friction-rollers, d, running on the arm B, as shown, and carries a pulley or gear-wheel, b, near its upper end,by means of which it receives rotary motion from one of the axles of the` car, truck, locomotive, wagon, or from some other suitablemechanism. To the lower end of the shaft is vsecured, a disk, D, which has a sharp edge, and which issuspended close above the railsv to be cleaned, or above the surface of the street. In the disk D are bearings for four, more or less, upright crankfshafts, E E. The upper ends of these crank-shafts carry pinions,-F F, which mesh into a stationary pinion, G, formed on or secured to the stationary arm B. I Thus, as vthe shafts E are revolved around the aile A, they are also, at the same time, revolved around their `own axles. To the disk are also pivoted, with their ends, four, or more or less, curved wings, H, which are, by meansof rods c, connected with the cranks on the shafts E. Thus, as 4the device isl set in motion, the wings will bedrawn in and pushed ont. v

The device being in front of the locomotive, the wings. will move all the obstacles lying on the disk D oit' the same, while the disk gathers allobstacles upon the surface of the rail or street. The respective diameters of the wheels Fand Gr determine how frequently the wings are movedout during each revolution of the shaft A. 'Y I The Vdevice shown in the drawing would .throw the snow to `one side of the track, and. would, therefore, be best adapted for clearing a double track. Where `two such devices are arranged in front of a car or other vehicle, the snow will be thrown to two sides. l

For clearing railroad-tracks, it is advisable to have suitable brushes, I I'. inA

' or to the framework of the vehicle, as may be desired.

I claim as new, and desire to secure by Letters Patent- 1. The application,'to a track and street-cleaner, of oscillating 'wi-ugs H H, operated by means of crank#- shafts E E, to which planetary motion is imparted, substantially as herein shown and described, and for the purpose specified.

A 2. The oscillating wingsvH, vwhen arranged upon and operating in combination with a revolving disk, D, all made and operating substantially as herein shown and described.

rear of the disk, for the pur- I pose of having the track completely prepared for traic. These brushes may be secured to a revolving shaft,

3.v The track-cleaner, when consisting of the revolving disk D, carrying the oscillating wings H,.in combi-v nation with the brushes I I, all made and operatingsubstantially as and for-the purpose specied.
